Toja/ZZ'. whom t Inlay concern/.f

Be it known that I,-LOUIs H. BRINKMAN, a citizen of the United States,residing at West Hartford, in the county of Hartford and State ofConnecticut, have-invented a new and use? ful Improvement in Radiatorsfor Motor-Vehicles, of which the following isa specification accompaniedby drawings forminga part. of the same, in wliich- Figure 1 is a frontview of'my improved radiator represented as, applied to a motor-vehicle.Fig. 2 is a verticalsectional view'on line 2 2, Fig. 1. Fig. 3 is avertical sectional view through oneend of the radiating-pipes, taken ona plane at right angles to that shown in Fig. 2; and Fig. lLis adetached view of one of the radiating-plates.

Similar reference-figures refer to similar parts in the dilferentviews.` i

My invention relates to that class of radiators which comprises upperand .lower waterchambers, between which the water to be cooled is causedto circulate'by gravity or aforced circulation through aseries ofserpentine pipes or restricted water-conduits, said pipes lbeing incontact with a series ofradiating-plates, by which theradiating-surfaceexposed to the air. is enlarged and the eficiency ofthe apparatus increased; and my invention consists vin the constructionand arrangement of parts, as hereinafter described, and pointed out inthe annexed claims. I- f v y I Referring to the accompanying drawings, ldenotes one of my improved radiators-mounted 'u pon a motor-vehicle andcomprising an upper Water-chamber 2, having an opening at theY top bywhich the apparatus may be filled cov' cred'with a cap 3. 4 is a lowerwatercharn' ber,` said chambers 2 and 4 being connected in the usualmanner with a water-circulating system which includes the jacketedcylinder of# an explosion-engine, and may also includefif desired, acentrifugal pump or othermeans for maintaining an active circulationthrough the radiating system. g

denotes one of a series of pipes communi-A cating at 6 with the upperwater-chamber 2 and at 7 with'the lower water-chamber 4, said parallelhorizontal sections 8, preferably Vconnected at their ends byreturn-bends 9. The several pipes 5.are preferably arranged side in Fig,2,` each being connected at its'opposite ends with .the upper* and lowerwater-chambers 2 and 4.. Strungupon the horizontal seetions 8 of thepipes are a'series of parallel vertical radiating-plates 10, one ofwhich is repsheet'metal whose length equals the vertical pipe beingreturned upon itself in a series of by side in the same horizontalplane, as shown i distance between the Water-chambers 2 and4 n and whosewidth equals the depth of the waterchambers'. These radiating-plates10also'serve as a reinforcement or stiffening of the pipes 5, which areotherwise held only at their ends, andthese plates also unite all thepipes of the` water-circulatory.system 'into a more or less rigidframework. Thisfunction of increasing l the rigidity of the pipes '5 isassisted by the fact that the plates 10 are fastened attop and bottom tothe water-chambers, The'plates 10v areprovided with openings 11 toreceive the pipes 5, Y

and the openings l1 are provided with annuylar anges 12, integral withthe plate 1'0 and formed by drawing a portion of the plate in theoperation of forming the opening 1414. By so drawing the annular'flangesa complete..

ring is formed in contact with the pipe, thus increasing the area ofradiation between the anges and the pipe and 'materially assisting thecooling of the water. A 12 are preferably punched from the plate 10alternately in oppositedirections from the top'v to the bottom of theplate, the upper series of openings for the water-pipes having their`annular'flanges upon one side of the plate and the next lower series o fopenings having ltheir "flanges upon the opposite sides of the plate.

The length of the annular lianges 12 is equal to the desired distancebetween the plates 10,

The annular anges.

so that when the plates are. strung upon the f water-pipes the -angesupon 'theplates are brought into Contact with the next adjacent i plate,as represented in Fig. 3. The upper- .and lower ends of the plates.are`preferably turned over t'o forrnanges 1313, which may be solderedto the surfaces of the Water'c'hambers 2 and 4, and the flanges 12 maylikewise bent into serpentine convolutions, said serpentine convolutionsbeing arranged in vertical and horizontal rows, of aseries of platesextending, from top to bottom'of the Waterpipes, eacli plate uniting allthe serpen tine cony volutons 1n said horizontal and vertical rows,

thereby securing said pipes in position.

2. In a radiator for'motorrvehieles, the combination with a seriesofwater-pipes forming annular flanges surrounding said pipes and in partof a Water-circulatory systermof a series Y of radiating-plates providedwith openings to "receive said series of pipes, each Aplate havingcontact therewith,lsaid Aannular anges being arranged'on opposite sidesof said plate.

3. .ln a radiator for motor-vehicles, the cornbinationwth a serpentinepipeA forming part of a Water-circulatory system, of a radiating-'plate-having openings'for separate convlutions of the pipe, saidopening provided with complete annular anges integral with the plateand'inl contact withsaid pipe.

per and a lower water-chamber, a series of lpipes connecting saidchambers, said pipes being bent into serpentine convolutions inter-'posed between said water=c`haxnbers, and a series of radiating-platesextending from the upper to 'the lower Water-chamber and having theirends attached thereto, said plates having a series of openings for saidpipes and a series of vannular flanges integral with they platesandinclosing said pipes. f
